Question

2y – 6x = -2
so y = 3x-1

y intercept is (0,-1) and slope is 3

But how do I find the second point on the line using slope please ?

Answer 1

Using slope? Well\[\Large slope = \frac{rise}{run}=\frac{3}{1}\]

Answer 2

Rise= y
Run =x

Answer 3

thanks but i still don't know what they did to get the second point of (3,-2) if you can let me know, im sure im just blind :)

Answer 4

Hmm, you sure it's (3, -2)?

Answer 5

oh.... no, i've gone wrong there !

Answer 6

(1,2)

Answer 7

There that makes more sense :)
Okay, so you know how the x intercept is \[\large (0, -1) => (x, y)\] right?

Answer 8

yep

Answer 9

that was y intercept ?

Answer 10

sorry, x intercept :)

Answer 11

Based on this point, what they did was go up 3 and over 1.
\[\Large slope = \frac{rise}{run}=\frac{3}{1}=\frac{y}{x}\]

So \[\Large (0(x), -1(y))+slope~3(\frac{3}{1}(\frac{y}{x}))=([0+1], [-1+3])=(1, 2)\]
